Note 1: This is valid for a tube with 14° anode angle. The HVL for a 22° anode is typically 0,5 mm
lower (@ 80 kV, 3 mm TF).
Note 2: The C3 and higher numbered calibrations are only available for product versions 2.0 or
higher.
Note 3: The C4 (GECT (7°)) is suitable for all GE CT tubes which have a 7° anode angle as well as
other manufacturers CT tubes and replacement tubes with a 7° anode angle. The C6 (GECT
(10.5°)) is suitable for GE CT tubes with a 10.5° anode angle..
